1、中文题目: 草垛沟5号煤层1.5Mt /a开采设计 英文题目:Mining design of caodugou No. 5 coal seam by 1.5Mt / a摘 要草垛沟矿井位于大同煤田西北边缘,地跨南郊、左云两区县,东距大同市40km,西距左云县20km。此矿地质条件简单,瓦斯含量较小,是低瓦斯矿井,适合采用综合机械化放顶煤采煤工艺。根据此矿地质条件与煤层赋存情况的综合考虑,决定使用倾斜长壁采煤法;根据矿井服务年限和可采储量的要求,确定矿井生产能力为150万吨/年;根据掘进,运输,通风等因素的限制,本矿拟使用采区式开采可满足其运料,通风,运煤三大系统的要求,并且拥有通风系统简单,
2、巷道布置简单的优点,优于采区式布置,故而采用。矿井达产时的首采工作面位于第一采区,工作面长度为220m,推进长度为1900m,回采工艺采用综放采煤法,采用“三八制”作业制度,采空区采用全部跨落法管理顶板。本设计包含内容八章,设计图四幅,参考文献13篇关键词:采区式;综放采煤;首采工作面ABSTRACTThe caoduanggou mine is located in the northwest edge of Datong coalfield, spanning the southern suburb, Zuo Yun two counties, east to Datong city 40
3、 km, west to Zuoyun county 20 km. This mine is a low gas mine with simple geological conditions and low gas content. It is suitable for comprehensive mechanized top coal caving. According to the comprehensive consideration of the geological conditions of the mine and the occurrence of the coal seam,
4、 it is decided to use the inclined longwall mining method; according to the requirements of the mine service life and recoverable reserves, the mine production capacity is determined to be 1.5 million tons per year; according to the tunneling, transportation, Due to the limitation of ventilation and
5、 other factors, the use of mining in this mine can meet the requirements of the three systems of transportation of materials, ventilation and coal transportation.It has the advantages of simple ventilation system and simple layout of roadway, which is superior to the layout of mining area, so it is
6、adopted.The first mining face is located in the first mining area, the length of working face is 220m, and the length of propulsion is 1900m. the fully mechanized caving mining method is adopted in the mining process, and the system of 3 / 8 system is adopted, and the roof is managed by the whole sp
7、an and fall method in the goaf.This design includes eight chapters, four drawings and 30 referencesKey words: mining area type; fully mechanized caving mining; first mining face目 录1 井田概述及井田地质特征11.1井田概述11.1.1交通位置11.1.2地理位置21.1.3气候条件21.1.4地震情况21.1.5经济条件21.2井田地质特征21.2.1勘探情况21.2.2地质概况31.2.3地质构造51.3设计煤层特
